<image>Context: This passage describes the albinism trait in rats:
Albinism is a trait in many animals that prevents the production of melanin. Melanin is a pigment that colors the skin, eyes, hair, and other body parts. The more melanin an animal has, the darker its body parts are. Rats with albinism lack melanin, so they often have white fur and pink eyes.
In a group of rats, some individuals have albinism and others do not. In this group, the gene for the albinism trait has two alleles. The allele for not having albinism (A) is dominant over the allele for having albinism (a).
This Punnett square shows a cross between two rats.

<image>Question: Read the following excerpt from a student essay. How can the writer best improve his or her academic voice?
Cloning has come a long way since a sheep named Dolly was successfully cloned in 1996. Now it is becoming possible to use cloning for a variety of purposes. For example, cloning technology could be used to grow stem cells from which replacement organs, such as hearts and livers, could be grown. If a person became ill and needed an organ transplant, cloning could provide the answer. With advances in technology, even cloning humans has become a distinct possibility. Scientists, bioethicists, and governments are all exploring this, even though it is clearly unnatural and unethical.

<image>Context: People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.
The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.
Matt was a mechanical engineer who was designing to record temperature, precipitation, and wind speed. The weather station would be used in a town where the highest recorded temperature was 40°C. Matt wanted to make sure the weather station would work even in unusually warm weather.
So, he set an indoor test chamber to 50°C with low moisture and no wind. He left the weather station in the chamber overnight. The next day, he checked to see if the weather station displayed accurate measurements after 24 hours at 50°C.
Figure: a weather station.
Question: Which of the following could Matt's test show?
Options:
A. how well the weather station would work when it was windy
B. if the weather station would work when the temperature was 50°C | B | false | |

There are two kinds of energy: kinetic and potential. Kinetic energy is the energy of a moving object. Wind and flowing water both have kinetic energy. Another type of energy is potential energy. There are different types of potential energy. You can think of potential energy as kinds of stored energy. For example, a compressed spring has elastic potential energy. If it doesn't have something holding it down, its energy will be released and it will spring forward.
Question: Which term matches the picture?
Options:
A. kinetic energy
B. potential energy | B | false |
